Edit feature line radius

I run into this problem frequently. How do I edit a feature line radius to
make it pass through a point?

In the screen capture you can see a curb bull nose that is not tangent. I
cannot get it to be tangent using the Edit Curve tool. Aside from breaking
the feature line and recreating the curve, how can I fix it?

Hi Neil,

There's probably a better way, but you could create an alignment which
has good pass through features and then trace over it to get the feature
line location.

Thanks for that idea Laurie. The situation is I created numerous feature
lines from an XREF. The curb radiii had been drawn with intermediate
vertices sometimes more than one. I need to go through all the radii and
remove the unwanted vertices, but doing so cause the arc to distort. I need
an efficient way to fix all those arcs. Perhaps I could explode them all and
use standard Autocad tools to clean every thing up. I'd have to create a
static surface to use to restore the elevations after the clean up. Still
that is a drastic fix when most of the arcs are fine.

This is one of those frustrations brought on by custom objects. I've posted
some CR's in the wish forum in regards to other problems with feature line
editing and fillets if you care to see what other issues I've faced.

As designers we need to focus our time and designing, not fooliong with
workarounds to make the tools do what they are supposed to do. I'm finding
this problem in every package I've tried lately. We in the civil field sure
could use more efficient offereings!

Click Home tab, Draw panel, Best Fit drop-down, Create Best Fit Arc .

You can find the radius by drawing a new arc.

That's a nice tool John.

Now if only we could use it to edit a feature line arc. I still have to
break out and delete all the bad feature line arcs, convert the new arc to
FL and re-join and regrade. If I had gradings applied it would be even more
work.

Would you not agree that we need better editing capabilities for FL arcs?

Yes Brian like that. My challenge is I need the arc to be tangent to the
driving lane of the parking lot. Can you do that?

Would you mind showing me how you do it with this file (2010 format)?

My apologies. I didn't notice you had a screencast with your last post. I
see what you are doing now. Quite a few steps there.

Thanks though.

By the way, the TAN TAN TAN circle tool doesn't seem to like 3D elements at
different elevations. Can you give it a go with the file I posted?

Hi Neil,

Saw those requests and thought here's an idea for a custom program
pending Autodesk doing something.

I may have some time available mid year to entertain myself with it.

It appears that you can't create it exactly tangent, but you can get REALLY close.

Beats erasing and redrawing... most likely.

Basically, just draw a polyline, create the circle, erase the polyline.

No worries. In figuring it out, I learned something new myself.

I think some custom tools would be a really handy for this stuff Laurie. I
seem to run into this a lot.

Not sure if you have control over how the field crew obtains the shots but the one point curve is designed for this situation. It is mentioned in several of the AU screencasts on field to finish and is shown about half way down on the "Curve Segment Codes" page in Help.
